To all whom it may concern: V

Be it known that I, CHARLES H. SMITH, a citizen of the United States, residing at Rockford, in the county of \Vinnebago and- State of Illinois, have invented certain new and useful Improvements in Apparatus for Priming Auton1obileEngines, of which the following is a specification.

The object of this invention is to produce a simple apparatus for priming automobile engines which will discharge a proper and definite quantity of fuel at each'operation and will distribute such quantity substantially equally among the cylinders of the engine, for the purpose of properly priniing each cylinder just before cranking or otherwise turning over the engine shaft in starting.

be positioned at any suitable point on the automobile above the level of the cylinders A, as for example upon thedash B. A pipe 2 extends from the tank 1 outwardly over the cylinders A, and has a plurality of branch pipes?) leading therefrom, onefor each of said cylinders. As shown in Fig. 5 the inner wall of the pipe 2 may be re cessed as at 2 around the openings into which the branch pipes 3 extend so that the fuel will flow into said branch pipes more readily.

Mounted upon each of the cylinders A is a member 4 comprising a portion 4 threaded into an opening in the wall of the cylinder, a valve casing 4", and a cup 4. The lower ends of the branch pipes 3 extend into the 'cup 4 for delive'ring'a charge of fuel thereto, and the member 4 has a passage 5 extending therethrough for conducting the fuel from the -cup 4 to the interior of thecylinder A.

Rotatably mounted in transverse opening 6 in each of the members 4 is a valve m mber 7, said member having a port 8 therein adapted to be brought into and out of register with the passage 5 by rotation of the valve member for controlling the flow of fuel through said passage 5. The valve members 7 are arranged to be operated simultaneously and to this end each is provided with an arm 9, the outer ends of all of said arms being connected together by a bar '10. A lever 11 which is pivoted at a suitable point as upon the dash B of the car is connected by means of a link 12 with the bar 10, so that the valves 7 may be controlled by said lever. A spring 13 tends to hold the valves -7 in their closed position.

A main valve 14, mounted in the pipe 2 adjacent the tank 1 provides means for controlling the flow of fuel from said tank. The valve 14: comprises in the present instance a conical casing 15 and a hollow conical valve member 16 fitting in said casing. The valve member 16 may be held to its seat by a coiled spring 17 surrounding a stem 18 on said valve member and bearing at one end against the valve casing and at its other end against a washer l9 and pin 20 carried by the stem 18. The casing 15 may be mounted in the pipe 2 in any suitable Way as by means of nipples 21 having passages 22 connecting the pipe 2 with the interior of the casing. Inlet and outlet ports 23 and. 24. in the wall of the valve' member 16 are adapted to be brought into register at different times with the upper and lower passages 22, oscillation of said valve member, for the purpose of first filling the valve member with the fuel from the tank 1 and then emptying-the charge into the lower portion of the pipe 2. Vent openings 25 and 26 in the casing 15 and valve member 16 are arranged to register at the time the outlet port 245 registers with the lower passage 22 so that air may enter the valve member 16 and permit the charge of fuel to' flow therefrom. As will be understood, the. size of the valve 14: is such that the amount of fuel delivered by it at one operation is just sufiicient to properly charge each of cylinders A, the charge being distributed to the cylinders by the pipes 2 and 3. 4

The valve member 16 may be operated by means of an arm27 thereon and a link respectively, by

28 connecting said arm with the lever 11.

' the lever 11 and its connections the valve member 16 is normally held in the position where the inlet port 23 registers with the upper passage 22.

The parts of the apparatus are so connected that by swinging thelever 11 forwardly or toward the dash B the mainvalve 14 will be opened to discharge a quantity of fuel into the lower portion of the pipe 2, and at the same time the valves 7 will be opened to permit the fuel to run into the cylinders A from the pipes 2 and3.

By providing the cups 4 air is admitted so that the flow of the liquid is free.

By meansof this apparatus the cylinders A are given substantially equal charges of the proper amount of fuel to priine them.

I claim as my invention:

1. In an apparatus for priming, explosive engines, a fuel supply tank, pipes conducting fuel therefrom to each of the engine cylinders, a valve controlling the low of fuel from said tank, said valve comprising a hollow rotary valve member adapted to first receive a definite quantity of fuel and their discharge such quantity at each operation, valves controlling the entrance of fuel into the engine cylinders, and means for operating all of said valves.

2. In an apparatus for priming explosive engines, a fuel supply tank, pipes for conducting'fuel therefrom to each of the engine cylinders, a valve adapted to control the flow of fuel from said fuel supply tank, a member carried by each of the'engine cylinders and comprising a cup adapted to receive fuel from said pipes, said member having a passage for conducting fuel from said cup to the interior of the cylinder, a valve controlling said passage, and means for operating all of said valves.

3. In an apparatus for priming explo: sive engines, a fuel supply tank, a main supply pipe connected therewith and extending above the engine cylinders, branch pipes each leading from said main supply pipe to one of the engine cylinders, a r0- tary valve in said main supply pipe, a pivoted lever, means operatively connecting said valve with said lever, a member carried by each of the engine cylinders comprising a cup adapted to receive fuel from its branch pipe, said member having a passage leading from said cup to the interior of the cylinder, a valve controlling said passage, means connecting all of said valves to said lever, and means tending to hold said lever in position to close all of said valves.

4:. In an apparatus for priming explosive engines, fuel supplying means, pipes conducting fuel therefrom to each of the engine cylinders, a rotary valve member controlling the flow of fuelfrom said fuelsupplying means and adapted to dischargqa definite quantity of fuel at each operation,

said valve having an operating arm, a. pivoted lever, a link connecting said armwith said lever, a rotary valve controlhng the entrance of fuel into each of the engine cyl-i inders, each of said valves having an opcrating arm, and meansconnecting all ofl the last mentioned arms w1th said lever. v

In testimony whereof I afiix my signature in presence of two witnesses.
